+
+For legacy reasons the options are not case sensitive.
+
+=over
+
+=item B<--continue>
+
+Do not stop for user interaction or on errors. (default: off)
+
+=item B<--debug>
+
+This option enables the output of debug information when running the
+various test commands. (default: off)
+
+=item B<--diff>
+
+Use C<diff -u> for comparing the expected output with the produced
+output. (default: use a built-in routine)
+
+=item B<--flavor>|B<--flavour> I<flavour>
+
+Override the expected results for results for a specific (OS) flavour.
+(default: unused)
+
+=item B<--[no]ipv4>
+
+Skip IPv4 related setup and tests (default: use ipv4)
+
+=item B<--[no]ipv6>
+
+Skip IPv6 related setup and tests (default: use ipv6)
+
+=item B<--keep>
+
+Keep the various output files produced during a test run. (default: don't keep)
+
+=item B<--range> I<n0> I<n1>
+
+Run tests between (including) I<n0> and I<n1>. A "+" may be used to specify the "last
+test available".
+
+=item B<--slow>
+
+Insert some delays to compensate for a slow host system. (default: off)
+
+=item B<--test> I<n>
+
+Run the specified test. This option may used multiple times.
+
+=item B<--update>
+
+Automatically update the recorded (expected) data on mismatch. (default: off)
+
+=item B<--valgrind>
+
+Start Exim wrapped by I<valgrind>. (default: don't use valgrind)
